My experience says that drivers and manuals you can find on the support site that belongs to the country where the notebook is produced.
It's not produced in North America so you should visit the website of the country where it was made, ie: Asia, Japan, Korea, Philippines etc.

If you bought it in Asia, check Toshiba Asia support site. If you bought in Japan, check Toshiba Japan support site, and so on.
